A striking complete refurbishment and extension of a tired 1980s house tacked onto the end of a late Victorian terrace in Cambridge. The overarching concept reimagines the building as a mews home, accentuating its differences to its neighbours. Extra space was found by borrowing from the rear garden, building an elegant single-storey extension to the back of the house. Generous new windows on the east and south walls, along with a crisp new west rooflight through the rear extension, fill the space with light. The new layout harmonizes the relationship between the various spaces, their uses programmed with svelte fitted furniture made from a restrained palate of materials – limed oak, white Carrera marble, and black limestone. The spaces are centred on a feature staircase of CNC-milled birch ply stained a rich red. Jewel-like in its double-height alcove, it seems to stand alone as a separate piece of furniture, signalling the heart of the home.
